Wavelet analysis as a tool to characteriseand remove environmental noisefrom self-potential time series
self-potential signals wavelet analysis
2015/9/14
Multiresolution wavelet analysis of self-potential signals and rainfall levels is performed for extracting fluctuations in electrical signals, which might be addressed to meteorological variability. I...
An overview on preseismic anomalies in LF radio signals revealed in Italy by wavelet analysis
LF radio-waves wavelet seismicity precursors
2015/9/1
Since 1996, the electric field strength of the two broadcasting stations MCO (f=216 kHz, southeast France) and
CZE (f=270 kHz, Czech Republic) has been sampled every ten minutes by a receiver (AS) lo...
Wavelet analysis of the LF radio signals collected by the European VLF/LF network from July 2009 to April 2011
Radio Network Wavelet precursors
2015/8/24
In 2008, a radio receiver that works in very low frequency (VLF; 20-60 kHz) and LF (150-300 kHz) bands was developed by an Italian factory. The receiver can monitor 10 frequencies distributed in these...

Wavelet analysis on adeles and pseudo-differential operators
Adeles wavelets multiresolution analysis pseudo-differential operators fractional operator
2011/8/31
Abstract: This paper is devoted to wavelet analysis on adele ring $\bA$ and the theory of pseudo-differential operators. We develop the technique which gives the possibility to generalize finite-dimen...
Wavelet analysis of corneal endothelial electrical potential difference reveals cyclic operation of the secretory mechanism
epithelial transport-electro-osmosis-electrophysiology
2011/9/2
There is evidence that the electrical potential difference of corneal endothelium (TEPD) is related electro-osmotically to fluid transport. Hence, determination of the TEPD would serve as a measure of...
On the Feasibilities of Using the Wavelet Analysis of Mueller Matrix Images of Biological Crystals

2011/4/21
The efficiency of using the statistical and fractal analyses for distributions of wavelet coefficients for Mueller matrix images of biological crystal networks inherent to human tissues is theoretical...
Cross wavelet analysis:significance testing and pitfalls
Cross wavelet analysis significance testing pitfalls
2009/11/11
In this paper, we present a detailed evaluation of cross wavelet analysis of bivariate time series. We develop a statistical test for zero wavelet coherency based on Monte Carlo simulations. If at lea...
